Abstract

The present disclosure is directed to systems and methods for using interferential stimulation to reduce or prevent symptoms of motion sickness in a closed system. In an embodiment the systems and methods receive an acceleration data stream, calculate parameters of interferential stimulation likely to cause the sensation of acceleration within a person's vestibular system that matches the acceleration the person's eyes perceive. The systems and methods deliver the interferential stimulation and measure a resulting head movement. The systems and method then compare that movement to a predicted movement. If the movement is not as predicted, the systems and methods update the parameters and deliver a second interferential stimulation until a desired affect is reached.
